Is there a way to force emails to texts to come from one number or be MMS from one number?
There is a post on here from 2017 that the solution is to simply use firstname.lastname@example.org but to me that doesn't work at all.
I use a service that checks servers and it sends an email to my phone number every time a switch or device goes down. It does it once per hour until the problem is resolved. Problem is, every time I get a notification, it's from a different number. Is there a way to fix this? I have a T-Mobile phone from my employer that had the same issue. I simply changed the notification message to a longer (160+ characters) and that problem was resolved. I tried doing the same with the AT&T service and had no luck. It's all still coming from another number.

The only way I have managed to get it to come from one number is to use <phone number>@mms.att.net, rather than the <phone number>@txt.att.net service. It usually works flawlessly, and doesn't cut up longer texts like the TXT service can. However, they appear to be having major issues with the MMS service today, reported by a number of people on here, so it might not be the best day to try it...
